World's fastest CPU

[Lepton87]

What CPU do you think deserves this title? I think making a few categories is necessary because different CPUs excel at different workloads.

1. Fastest at serial workloads/having the most throughput
2. Very high throughput while still maintaining very good serial performance. I think we can devise a formula that would take into account both numbers and weighted them properly.

My contenders:

Intel Xeon Processor E7-8890 v4
IBM Power 8 12C 3.52 GHz
and I read someone claiming SPARC M7 is the fastest but I don't know much about that CPU. Does anyone have its benchmarks? I only found benchmarks made by the manufacturer. Architecture overview?

http://www.anandtech.com/show/10435/assessing-ibms-power8-part-1

the benchmarks show that Xeon and Power8 are extremely close.

I think that while power 8 was faster then Xeons when it was released it got surpassed on average by 24C broadwell both in ST and MT. The race is close and both CPUs have different strengths so it all comes down to a specific benchmark but I think it's safe to say the Xeon E7 is faster ON AVERAGE. It's hard to compete with a CPU with twice the number of cores. The match-up is still closer than it might look at first. Power 8 is made to juggle at least 4 threads with the capability to work with 8. Due to huge gains from HT on the order of 100% it's not completely outclassed by the Xeon with twice the number of cores but only about 20% gain from HT. Its 12 cores were enough to be faster than a Xeon with 50% more cores but twice as much is too much to overtake.

Looks like the E5-4669 v4 are the fastest general purpose CPU's.

What about IBM Z-Series specifically IBM z13? 4B Transsistors 5GHz 676mm2. In addition to that every three such CPUs share a SC chip that adds 480 MB off-die L4 cache. I haven't seen any benchmarks but to me it seems that it should outperform Xeons in serial code and moderately threaded workloads. Maybe I didn't write it clearly but I'm not looking for a throughput monster only.
UPDATE:

Total of 4MB L2 cache per core. That's insane! ST performance should leave any Xeon in the dust.
Anyone knows the power consumption of this thing?

It would be awesome if Johan De Gelas review a mainframe computer like this IBM Z-series. They are a big mystery to me I have never read a review or even benchmarks of IBM Z-series computer. When I made my thread I haven't even thought about that Z-series CPU.

Sweeet! Struggled to get my 2700k over 1.6 petahertz without resorting to −272.15 Kelvin Kooling. I'd ask what your thermal secret is, but....aliens.

I wouldn't buy anything over 6700K, minimal gains probably even if your primary need is speed. Do not encourage people to waste $$$! lol

Power 8 top bin. But it uses a trillion of watts.

 

[Lepton87]

Isn't z13 faster? Power 8 strugles with the latest 24 cores E7 Xeons.

A 6700K produces the fastest Octane score, the fastest Jetstream score, the fastest Sunspider score, the fastest Peacekeeper score, the fastest Kraken score, clearly it is the fastest processor. You can go more parallel if you want, but that is a never ending road that leads to supercomputers.

Didn't knew it. Such a monster.




Power 8 surpass the Xeon in loads that excel in the yielding of its SMT8 capacity.

It all comes down to using the right tool for the right job. If your test was moving 50 people 100 miles, a schoolbus would look like the world's fastest car when compared to a 2 seater exotic.

It's clear that he keeps his CPU cold with solution.

(sorry, had to drag that out of the dustbin)

How would it compare to z13 in those workloads? Clearly there's the ISA difference but assuming the best optimization within reason? (obviously using the fastest compilers?)
ps. the 6700K lacks multi-threaded performance by way to much for me to have even considered it

Looks like the E5-4669 v4 are the fastest general purpose CPU's.

but that looks like quad 4669's, if we're talking 1 single cpu package 2669 is faster (higher turbo/tdp). A bargain at 4.7k haha https://www.amazon.com/Intel-CM8066...7_3?ie=UTF8&psc=1&refRID=E3TGBTNGCT9WP1T9QMHP
E5 scores are for dual 2669 actually too..

Actually the fastest Intel Xeon is the E7-8890 v4 it works at the same frequency as that 2669 but has an additional 2 cores not to mention the ability to work in 8S systems. That one is a real bargain at over 7k USD. That 2669 looks cheap compared to that.
